Description

The event recorder device

The utility model relates to a kind of event recorder device, particularly, relates to when particular event such as motor traffic accidents take place or overpass is collided or the traffic intersection red light is bright or knotmeter measurements in speed limit highway section when overspeed of vehicle is arranged, the device of the image at record scene.

Usually, during automobile generation traffic accident, when no conclusive evidence and both parties' statement is conflicting, determine that accident liability is very difficult.In the configuration of existing automobile, do not write down the device of the scene of the accident, as black box, therefore, accident both sides often are is that the accident who causes is respectively held a speech.In addition, bridge such as overpass often are damaged, and breeder is usually escaped, if the on-the-spot eye witness who does not have the video recording unit of traffic management system or be ready to testify maybe can become the similar record of evidence, it also is very difficult handling this class accident.And continual video record needs a large amount of resources, also needs running check video record, is very time-consuming find out useful video section from a large amount of video records especially.In addition, at modern society governed by law, traffic management system will be administered the state according to law, the means of existing traffic management system are obviously undesirable, if party concerned and traffic management system dispute, under the situation that traffic management system is difficult to put to the proof, if administrative litigation is arranged, can not put to the proof at traffic management system, traffic management system will face the situation of losing a lawsuit.In addition, the chaufeur that identifies oneself not traffic violation also needs evidence to prove that its behavior is legal.And in all traffic highway sections recording device is installed all obviously is unpractical, and it also is very difficult handling this information.In addition, limit some people at needs, as the marquis that goes bail for examines or family in child, action radius, also need to write down some data constantly.If only write down the data of the incident front and back certain hour of being concerned about, not only saved resource, also make the inquiry data relevant become very simple with this incident.

Therefore, need a kind of device, can when traffic accident take place, only record takes place before the traffic accident and the information of certain hour afterwards, as image.In addition, by the triggering in the external world, as utilize the remote controller switch, the information of certain hour before record triggers and afterwards as image, will more have foundation for the processing of traffic violations.For example, on the expressway, if overspeed of vehicle, the speedometer on the expressway by this information of remote control trigger device trigger recording device recording, comprises image after finding hypervelocity, and this device can be installed in automobile or high speed roadside.And for example, at overpass, if automobile and bridge collide, device can write down the information before and after the collision.

In addition, said apparatus is passed through the internet, or private communication monitoring network, or public telephone network, or mobile radio communication is connected with supporting with it monitoring and control centre, for example, each automobile is assigned a webpage under the traffic network address, and monitoring and control centre is the situation of all automobiles in the monitoring network at an easy rate.

Also have, chaufeur and user can login the traffic network address, finish data exchange, control etc. by the internet.

5. in case when accident took place, bump triggered acceleration pick-up, the black box internal battery continues to record the image scene of 10 seconds kinds with assurance device, and quickflashing store device then, the electric connection of cut-out and controller.

In case after this 12VDC power up is normal, device will enter playback state automatically, recorded video image in the loop play internal memory.

The element cost of this device is about:

Camera: RMB340

Controller: RMB830

Black box: RMB830

Fig. 8 is for realizing the circuit diagram of this utility model.Wherein, acceleration sensing switch 810 is as acceleration pick-up, and acceleration sensing switch 810 comprises fixing electrical pickoff 811 and the electrical pickoff 812 on the arm on the pivot, and an object (not shown) that certain mass is arranged is arranged on the arm on the pivot.Generally, electrical pickoff 811 does not contact with electrical pickoff 812, electrical pickoff 811 is received high level, and electrical pickoff 812 is received the input end 822 of a phase inverter 820, and the mouth 826 of reverser 820 is input to the low level down trigger end of CPU126 (model is 80C31).When acceleration change takes place, because action of inertia makes electrical pickoff 811 contact with electrical pickoff 812, make mouth 826 output low levels of reverser 820, and then make CPU126 control that the data in the internal memory 125 are write flash memory 135.Other function is existing the description in Fig. 1, here, repeats no more.

Though described utility model by accompanying drawing, should know, information acquisition device and flip flop equipment can be any type of device that can respond to certain variation, as switching value, electrical quantity, temperature parameter, time parameter and any sensor of sound sensor, brightness sensing, odor sensing, coal gas amount sensing, door.In addition, the utility model also can be used for the monitoring as bank, and as only just recording picture and data when the mutual dealing, image can comprise the depositor, attendant, and data can comprise counting instrument data at that time etc.Also can be used for protective device, when protective device is triggered, record data and image.

Those skilled in the art can make many improvement and distortion that do not break away from the utility model spirit and technical scheme, as information acquisition device and flip flop equipment under certain condition, can be same device, not only obtain information but also satisfy flip flop equipment under the certain condition in the information of obtaining, therefore, wish that appended claim can cover all these classes and improve and distortion.
